Hello everyone,
Citroen xantia 1.8 petrol,
Failed on CO slightly too high,
Both side repeaters not working properly,
And the strange one,
The front anti roll bar had traveled sideways so one side was rubbing against the subframe.
So get the multimeter and lexia out to test the 02 sensor,
New bulbs,
Loosen the roll bar clamps and reposition it using the appropriate tool of course

Re: MOT Fail
That's very unusual on the roll bar Peter... Never seen that before... Check its bushes...
Yep, Lexia to check function of the O2 Sensor. If it looks normal on Lexia live data then the cat has likely lived its ninth life.
Odd that both side repeaters have died. Ask for wiring diagrams and look for something common between them.

I take it that will be the minor adjuster, 7lb lump hammer.

Re: MOT Fail
If this is the 8v version there was actually a TSB years ago for failing emissions test. Cant remember what part of it was too high but the solution was to unplug the injection ECU for 30 minutes, Re fit & repeat the test. Normally done the trick.

Re: MOT Fail
Ahh yes, Indeed, I remember now. It's a bit dim now but I seem to recall there was also a wiring modification involving ECU earthing and specifically the oxygen sensor heater wiring.
Peter, it may well be a good plan to look at the sensor heater voltage at the sensor connector and check you're seeing the full 12v there...

Re: MOT Fail
Hello again,
Very strange Jim, i will be checking them when I loosen them. The 02 sensor was reading in milliamps on my launch tool, still learning Lexia so I use them both,at least with the launch tool I can't totally kill anything, one of the bulbs had just gone white, the other had a broken connector in the mounting, new one arriving Monday. New 02 sensor and cataclean going in again on Monday.
Paul, I don't know it's weight but definitely lumpy, with a little help from a crowbar.
Wheeler, it's a 2000 16 valve mk2.
Thanks all, hopefully get it all done on Monday, my MOT place is very good, they'll put it on the emissions tester before re mot, the guys also show me what they've failed it on.

Re: MOT Fail
If its a late 16v it probably wont apply then. It was mk1 1.8 8v versions that were affected.

Re: MOT Fail, Now passed
Well after a busy few days, 2 new control arms, I think that when I went round bends the rear of the arm was moving and touching the roll bar, i'll be keeping an eye on it, the old bushes were rather shot.
New catalyst, new dust covers, 1 new sidelamp mount and 2 new bulbs.
Passed, Xantia motoring for another year.
